Abstract:The research status of the main methods, characteristic, interaction of microstructure and mechanical properties and their application of micro-nanometer processing technology for biomedical ultrafine grain titanium materials were described. The latest progress in micro-nanometer processing for independent development of a new near β TLM (TiZrSnMoNb) biomedical titanium alloy was focused on. And the future trend on research and development of biomedical titanium alloy was proposed.
Key words: titanium alloy; biomaterials; micro-nanometer processing; ultrafine grain; biomechanical compability
